British teenager Lewis Clarke has been officially recognised by Guinness World Records as the youngest person to trek to the South Pole.
Lewis, who attends Queen Elizabeth's Hospital School in Bristol, was 16 years and 61 days old when he reached the Geographic South Pole on 18 January earlier this year, having skied 1,123.61 km (698.18 miles; 606.7 nm) from Hercules Inlet on the Ronne Ice Shelf.
The intrepid young adventurer was joined by experienced polar guide Carl Alvey, 30, for the unsupported trek, meaning only human power was used to move forward, with no wind, animal or motorized vehicle power.
During the attempt, Lewis skied for an average of eight hours a day and had to withstand temperatures as low as -40C (-40F) and winds of up to 120mph (193km/h).
As well as helping him earn a place in the history books, Lewis’ trek has also so far helped raise over £3,000 for the Prince's Trust charity.
On Friday, Lewis will be visiting the Guinness World Records offices and we’re giving you the chance to ask him questions about his incredible feat.
You can leave your question in the Facebook comments at the foot of the article or tweet them to @GWRnews with the hashtag #askGWR.
We’ll be putting the pick of the questions to Lewis for a video which we’ll be publishing on this site and our YouTube channel next week.
UPDATE: Thanks for all your great questions - look out for Lewis's answers to your posers in a video feature next week on www.guinnessworldrecords.com
